IMPROVEMENT IN CAR-COUPLINGS.

Specification formi'n g part of Letters Patent No; 45,509, dated December 20, 1864 antcdated December 9, 1864.

To all whom it may concern:

Be it known that I, B.-F. MARsDEN, of Galena, in the county of J 0 Davies and State of Illinois, have invented a new and Improved Car-Coupling; and I do hereby declare that the following is a full, clear, an'd exact description thereof, which will enable any one skilled in the art to make and use the same, reference being had ,to' the accompanying drawings, making a part of this specification, in whichv Figure 1 is a side sectional view of my invenlion, taken in the lzne m w,'Fig. 2; Fig.2,

' a horizontalsection of the same, taken in the line ljy, Fig. l. I

Similar letters of reference indicate'corresponding parts in the two fi gures.

This invention consists in having each draw-head of a car provided with two open-- in gs, one of which has a link permanently se- /cured in it, and the other provided with a jointed pin to catch and hold the permanent link of the'draw-head of the adjoining car, all being arranged as hereinafter described, whereby two cars are connected by two links,

neither of which is detachable from its draw head, and a selt coupling at the same time obtained, and one which will admit of being veryreadily uncoupled.

A A represent the adjoining draw-heads of two cars. Each of these draw-heads is provided with two openings, a a, in one of which, a, a link, B, is permanently secured by a pin, 1). In theother opening, a, there is a vertical adjustable pin, 0, composedof two parts, d, connected by a joint, 6. The'pins G areallowed to move vertically in the draw-heads- "that'is to say, they may be raised and lowered therein-41nd the upper parts, 0, are provided with a shoulder, f, and these shoulders rest on the tops of the draw-heads and support the pins 0, the lower ends of the parts (1 being in slots 9 in the bottoms of the draw-heads, the back part of said slots being beveled or inclined to admit of the parts 6 swinging backward. The front ends of the slots 9 are vertical and serve as stops for the parts d and prevent them being drawn forward. or outward toward the mouths of the draw-heads, as will be fully understood by referring to Fig. 1.

The pins 0, in consequence of being formed of two parts connected by a joint with the lower ends in the slots g, admit of the'links B' connecting themselves with said pins as the former enter the openings a, and it will be seen by referringto Fig. 2 that the link 13 of one draw-head is opposite the opening a--ot;

the adjoining draw-head. By this arrangement the two draw-heads are connected by two links instead of but one, as hitherto, and

a more secure attachment obtained with permauent linksor those which do not require to be detached from the draw-heads, and the draw-heads are rendered self coupling', in consequence of the links B forcing back the lower parts, 12, of the pins U, and said parts (1 drop-' ping into or through the links when the outer v ends of the same pass them. I

- In order to detach the draw heads, all that is required is simply to raise the pins 0, either directly by hand or through the medium of any suitable appliance. The links not bung detachable in either draw-head, the trouble and embarrassment attending the losing of a link is obviated.

Havingthus described my invention, what vI claim as new, and desire to secure by Letters :Patent, i's- The two openings a a in the draw-heads "A A, in combination with the two liiiks B B and the removable or rising and falling jointed pins 0 0,51 arranged'substantially as and tor the purpose herein set forth.
